Abstract (en)
A disposable infusing device for ambulatory patients comprises a disk-shaped cover plate (18) and a disk-shaped impeller plate (32) which are interconnected by a stretched membrane (38) that joins the edge of the cover plate with the edge of the impeller plate. The effect of the membrane is to urge the plates into juxtaposition. A fluid port is formed on the cover plate for fluid communication through the port (2) with a collapsible fluid chamber (36) established between the plates. Fluid when injected into the chamber between the plates, is subsequently expelled through the port for controlled infusion to a patient as the membrane pulls the plates toward each other to collapse the chamber.
